HANGER FOR sLIDING nooRs.

Application filed April 12, 1924. Serial No. 705,972.

rThis invention relates to sliding doors9 and particularly to hangerstherefor.

A.Agn object of the invention is to provide a sliding door hanger havingimproved provision for preventing the accidental removal of the doorfrom its track.

Another Aobject is to provide a strong, sturdy hanger which is simple inconstructionA and which also may readily be disassembled to inspect orrepair the same.

An important feat-ure of the invention is the provision in a hanger of aframe so shaped that it AvWill prevent the removal of the door from thetrack by a vertical movement, preferably at all times but particularlywhen the door is closed.

` @ther important features are the pr0- vision of a hanger which cannotbe disassembled 4vvhen in its. position on the track, but Whichmay bereadily disassembled when removed from the track and the provision thehanger of means for adjusting the height of the door from the floor.

The invention is particularly useful When applied to fire doors,inasmuch as it insures that the door will remain closed in time of lire,vvh'en its opening would be at once most harmful in its effects and mostprobable to occur. When there is a fire on one side of the door, forexample, the door Will be eX- panded by the h'eat of the fire and thedoor andv its mountings Will tend to be Warped or shifted so as to causethe door to be lifted olf its track unlesspositive means to hold it inplace are provided. Again, if the retentive action of the hanger is madeto depend upon any pins, screws', or` other unsubstantial members7 theheat of the lire vvill tend to melt or to Warp these members and thus toldestroy their effectiveness. Moreover, When screws are employed toprevent the removal of the door, there is a tendency on the part of theWorkmen who set the door inl place to omit to insert the screws, Whichomission ivill in all likelihood not be discovered until va're has movedthe door oil of its trackand caused great damage to thev-vproperty whichwould otherwise have'beenprotected by the door; v

Fig. 3 is a front vieiv of the hanger.

Fig. 1 shows a fire door 5 of any suitable construction slidably mountedby means of hangers G on a track 7 extending above an opening 8 in aiireproof ivall 9. The track 7 is sloped toward and over the opening Sso that when the door is not` held open it will slide along the track tocover the opening. The door is preferably shaped with its top inclinedto conform with the slope of the track7 and is normally. maintained openby means of a Weight lO'on the end of a chain 11 which extends over apulley 12 and is fastened to a brace 13 on the door 5.

ln the chain, near the narrower end of the door, is a fusible linkllwhich in case of a fire on either side of the door will be melted so asto release the door and allow it to slide closed. Otherdoor releasingmeans, either immediately or remotely controlled, may obviously he used.A stud 15 set in the floor outside of the door and carrying a roller 16acts to prevent outward movement of the door. As long as this stud is inplace, the construction of the han-ger vto be described belovv Will`prevent the door from being moved from the track. A pair of stops 17 arefastened to the Wall 9 to prevent the door from sliding aast the opening8 or beyond the stud 15. n the track 7 are a pair of kprojections 18positioned under the hanger `6 when the door rests against the stops 17,s hovvnin 2 theheads of bolts19 used tofasten the track on thejvall..The here@ Gilliistlietectn ,Fiss 2. and '53 comr'njises y a hook-shapedframe 20 fastened einem 21 roi the -ciorf bytes 21a ...The

but that, when the door is moved outwardly trom the wall, the distancebetween the bottoni ol' the track and the inner sloped-oli1 portion ofthe end 21 will be sutlicient to allow the removal oi the slieave fromthe track. To permit this removal, the track should be set out from thewall enough so that the hook oit the frame 2O mav be moved to vard thewall, and the vflanges oi' the sheavc should be beveled in the mannershown. [i saddle 2/1 is slidably held in the hook of the traine 20. Asheave or roller 25 turns upon a. journal 26, which is slidably fittedthrough the sides of the saddle. rlhe sheave comprises bushing` in whicha groove 28 is provided to retain lubricating` material. rlfhe sides 29ol" the saddle lient over the hook oi the casting so as to prevent thesaddle from being slid horizontally out el' the hook. The sheave 25 isadapted to ride on the track and is set thereupon by a suitable movementot' the door belore the stud 15 is fastened in the floor outside thedoor.

ln o der to further insure aga-inst the she-ave beinglifted off thetrack by the vertical movement of the door when it is closed, a shoulder8O is formed on the frame 20 so as to be beneath the projection 18 whenthe door is against the stops 17. The position of this shoulder may, ofcourse, be varied in accordance with the requirements of the door. ltmay be formed nearer the track 7 and the bolt 18 in case it is desiredto more etlieetually prevent the raising o t the door, and it may beplaced further away 'from them it it is desired to more effectivelyinsure against the catching thereof against the bolt 18 when the door isslid into closed position.

ln order 'to allow the height of the door to be adjusted when it is putin place or at any time thereafter when the shifting' of the floor orthe wall or the sagging of the door renders this necessary, anadjustable screw 35 is inserted in a threaded opening in the top ot thehook oi the casting. @n the screw is an annular shoulder 36 to take thethrust or the saddle and a reduced portion 82' er;- tending into thesaddle. The screw 85 may be provided with a head 88 to more readilyallow its adjustment. ln order'to lock the screw after the height ot thedoor has been adjusted and in order to hold the saddle and the sheavewithin the hook of the frame while the door is being set upon the track,a set screw 39 is )rovided in the top o'l the saddle and is positionedso that it may be set into a groove 110 on the reduced end 87 of thescrew 35. The employment of the adjust-ing means above described enablesthe track 7 to be set in any convenient position letten has obstructionssuch as projections formed on the wall or reinforcing means for the wallwhich prevent the track 'from being` attac iedto the wall in a positionexactly in accordance with the height or" the l the use of myadjusting,` means, the traermay be placed on the wall so as to avoid allsuch obstructions without the ne- `,'ty altering` the size ot the doorto conform i Yith the position of the track. Furthermore, when the doorlis in place the disassembly oi a 'hanger oithe construction shown bylire or other causes is practically impossible, though the hanger may bereadily disassembled aiter the door is removed from the track.

lt', for any reason, it is desired to remove the door from the track,the stud 1o must lirst be removed from the Hoor and the bot tom of thedoor is then swung outwardly about the points of engagement of thesheaves a5 with the track 7 until the ends 21 of the frames 20 are outfrom below the track. The door is then raised so that the ianges or' thesheaves will clear the track. rhe frame, the sheave, and the saddle 'oft tl e hangers 6 are so constructed that each o1 even after the door isremoved from the track and the set screw 39 loosened, the hanger cannotbe disassembled until the journal 26 has been slid out of its bushing27. An opening l2 is provided in the trame at such position that it willnormally be opn posite the projection 18, but when the sheave rests onthe end 21 oli' the frame it will be opposite the journal 26 to morereadily enable the removal ot the journal by the insertion ol a toolthrough opening 112. The re moval of the ournal releases the sheave fromthe saddle, which. is then raised and the sheave slipped out of thetrame, after which the saddle may be again slid downwardly and removed.

The permanent construction of the hanger is exceedingly important whenthe hanger is likely to be exposed to lire or other causes which wouldtend to disasseinble hangers of a less permanent character. Theinvention is, of course, not limited to the particular embodimentsthereof illustrated and described.

1. In a door hanger for sliding doors, a frame having a hook-shapedportion at one end thereof and an offset portion at the opposite endthereoi':I located opposite the recess between the sides of thehook-shaped portion, a sheave`r a sheave saddle slidably mounted in thehook-shaped portion ot' the frame, the length of the radius of thesheave together with the length of the sheave saddle being greater thanthe distancev bevtween the end of the hook and said 'o'set portion fromthe fra-me, whereby the Sheave saddle and sheav-e are prevented fromreinoval from the traine until the shea've is removed from the saddle,and means permitting removal of the sheave from the sheave saddle onlywhen the sheave and saddle occupy a certain position in the frame.

2. In a sliding` door hanger, a frame having a hook-shaped portion, a`sheave saddle and sheave slidably mounted Within the hookfshapedportion, a shaft on which said sheave is mounted, said shaft beingretained in position bv engagement of its ends With the walls of thehook-shaped portion of the frame, the :trame having an opening,- throughwhich, when the sheave saddle has been` moved from its normal positionto a certain other position in the frame, into which it is movable whilethe trame is attached to a door, the .shaft may be removed from thesheave and sheave saddle to permit the disassembly of the hanger.

3. In a door hanger for sliding,` doors, a frame having a hook shapedportion, e saddle slidably mounted in the heel; shaped portion of theframe, a sheave rotatably mounted in the saddle, and means on the framefor preventing the saddle and sheave from being removed from the frameWhile the saddle and sheave are in assembled relation.

il. A frame having a hook shaped portion, a saddle slidably mounted inthe hook shaped portion of the frame, a` slieave rotatably mounted onthe saddle, means for preventing the saddle and sheave from beingremoved from the frame While the saddle and sheave are in theirassembled relation and means for enabling the frame and saddle to bedisassembled While the trame is attached to a door.

5. n a door hanger, a frame having a hook-shaped portion and an oii'seton the same side of the frame as said hook-shaped portion for engagementwith the track to prevent derailment, a sheave saddle slidably mountedon said frame, a sheave rotatably mounted on the saddle, and means foradjusting` the saddle to adjust the distance of the sheave from saidoffset.
